Electric utility companies depend very much on simulating the performance of the electric power system with various types of software, because field tests cannot easily be done. There are software tools for studying the normal flow of power through the transmission lines. There are also computer programs for simulating disturbances to the power system caused by external events such as lightning strokes, or internal events caused by switching etc. The transients caused by such disturbances can be very fast, in the microsecond or millisecond range. They are simulated with "electromagnetic transients" programs. The disturbances can also be slow, in the second and minute range. They are simulated with "stability" programs.

电力公司非常依赖于使用各种类型的软件来模拟电力系统的性能，因为现场测试不容易进行。有一些软件工具可以用来研究输电线路中的正常电力流。也有计算机程序用于模拟由外部事件（如雷击）或由开关等引起的内部事件引起的电力系统干扰。由此类干扰引起的瞬变可能非常快，在微秒或毫秒范围内。它们是用“电磁瞬变”程序模拟的。干扰也可以很慢，在秒和分钟范围内。它们是用“稳定性”程序模拟的。
